DETAILED DESCRIPTION

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0034] like Figures 1 to 10 The adjustable auxiliary scaffold for interior decoration shown in the figure comprises a support pedal 1 and support legs 201 rotatably connected to the four corners of the bottom surface of the support pedal 1, and also comprises an adjustable handrail assembly, the handrail assembly comprises: Two movable seats 2, the two movable seats 2 are respectively slidably connected to both sides of the supporting pedal 1; Two handrail frames 3, the handrail frames 3 are rotatably connected to the movable base 2, and a handle 4 is detachably connected between the top ends of the two handrail frames 3; An auxiliary support component, the auxiliary support component includes an auxiliary support frame 5 rotatably connected to the handrail frame 3, when the handrail frame 3 is turned over and is in a vertical state to be supported, a tripod structure is formed between the auxiliary support frame 5, the handrail frame 3 and the movable seat 2; The locking assembly is used to synchronously lock the states of the auxiliary support frame 5 and the armrest frame 3 to maintain the stability of the tripod mechanism.

[0035] It should be understood that in the process of using the scaffold, the four supporting legs need to be flipped and unfolded from the four corners of the support pedal 1 to form a supporting state, and then the handrail frame 3 is flipped so that the handrail frame 3 is flipped to a vertical state to form a vertical state with the moving seat 2, and then the handle 4 is detachably connected between the tops of the two handrail frames 3, thereby realizing the setting of a supporting mechanism on the scaffold, which not only satisfies the foldable storage in the storage state, but also realizes the function of providing support when in use, which is conducive to the staff to work safely under control; It should be further explained that when the handrail frame 3 is flipped to a state perpendicular to the moving seat 2, the two ends of the auxiliary support frame 5 of the auxiliary support assembly respectively form a tripod structure between the handrail frame 3 and the moving seat 2, and under the action of the locking assembly, the stability of the handrail frame 3 relative to the moving seat 2 is further enhanced, which is conducive to providing stable support for the staff; It should be further explained that after the locking assembly is locked, the tripod structure formed between the auxiliary support frame 5, the armrest frame 3 and the movable seat 2 is locked to maintain the stability of the tripod mechanism and the stability of the supporting state. When folding and storage is required, the locking mechanism can be unlocked for easy use.

[0036] As a further embodiment of the present invention, it also includes: Two first slide grooves 6, which are respectively provided on both sides of the support pedal 1 to provide sliding support for the moving seat 2; Two extension platforms 7, the two extension platforms 7 are respectively fixedly connected to the two sides of the support pedal 1, and the edges are provided with connecting slide grooves; Two first support shafts 8, the two first support shafts 8 are respectively movably plugged into the bottom ends of the handrail frame 3, one end of the first support shaft 8 is rotatably connected to the moving seat 2, and the other end is rotatably connected to the first slider 9, and the first slider 9 is slidably connected to the connecting slide groove; Two second support shafts 10, the two second support shafts 10 are movably connected with one end of the auxiliary support frame 5 at the corresponding position away from the handrail frame 3, and the two ends are respectively fixedly connected with a third slider 11 and a fourth slider 12, and the third slider 11 and the fourth slider 12 are respectively slidably connected with the edge of the movable seat 2 and the connecting slide groove; When the handrail frame 3 is flipped over and in a vertical state ready for support, the locking assembly locks the position of the fourth slider 12 , thereby locking the handrail frame 3 in a vertical state relative to the moving base 2 .

[0037] It should be understood that after the fourth slider 12 is locked, the position of the fourth slider 12 on the moving seat 2 will be positioned, so that the two ends of the auxiliary support frame 5 are positioned, so that a stable tripod mechanism is formed between the armrest frame 3, the moving seat 2 and the auxiliary support frame 5, which is conducive to maintaining the stability of the vertical state of the armrest frame 3 relative to the moving seat 2, and thus providing stable support for the handle 4; It should be further explained that when storage is needed, the lock on the fourth slider 12 is released through the locking assembly, and the armrest frame 3 is flipped over so that the armrest frame 3 is flipped over and folded toward the movable seat 2, and the auxiliary support frame 5 is also folded synchronously. During the folding process, the fourth slider 12 and the third slider 11 will slide in the connecting slide groove and the edge of the movable seat 2 respectively, providing the degree of freedom required for folding, and after folding, the armrest frame 3 can be pushed into the first slide groove 6. During the process of the armrest frame 3 and the auxiliary support frame 5 being pushed into the first slide groove 6, the first support shaft 8 and the second support shaft 10 always maintain support for the armrest frame 3 and the auxiliary support frame 5.

[0038] By providing a foldable handrail frame 3, a support point is provided for the support pedal 1. When storing, the handrail frame 3 can be folded to maintain regularity, which is conducive to reducing the difficulty of later storage. In addition, the handrail frame 3 can be moved to the inside of the edge of the support pedal 1, which is conducive to further reducing the space occupied.

[0039] As an optional embodiment of the present invention, the locking assembly includes: A rotating disk 13, the rotating disk 13 is rotatably connected to the top of the third slider 11 and fixedly connected to the end of the first support shaft 8, and a first clamping groove 1301, a second clamping groove 1302 and a third clamping groove 1303 are formed on the surface of the rotating disk 13; The handrail frame 3 is slidably connected to the surface of the first support shaft 8 along the extension direction of the axis of the first support shaft 8 to achieve synchronization of rotation along the axis of the first support shaft 8; A snap-in pin 14, which is slidably disposed on the side wall of the armrest frame 3 to engage with the first snap-in groove 1301; A support rail 15, the support rail 15 is fixedly connected to the surface of the first sliding block 9; The card seat 16 is slidably inserted into the support rail 15 and supported by the support rail 15 through an elastic support member; The linkage pin 17 has one end fixedly connected to the clamping seat 16 and the other end slidably inserted into the third clamping groove 1303 .

[0040] It should be understood that in the process of flipping the armrest frame 3 to reach the vertical moving seat 2, the fourth slider 12 will approach the seat 16 until it reaches the position of the seat 16, and the seat 16 will be pressed so that when the fourth slider 12 moves to the top of the seat 16, the pressing is cancelled. Under the support of the elastic support member, the seat 16 will clamp the fourth slider 12 to form a limit, and insert the linkage pin 17 into the third slot. On the one hand, the tripod mechanism is locked, and on the other hand, the vertical state of the armrest frame 3 is further positioned.

[0041] It should be further explained that when the armrest 3 is pulled out from the first slide groove 6, the linkage pin 17 is in a state of being plugged and limited with the second clamping groove 1302. After the armrest 3 is pulled out, the clamping pin 14 is plugged into the first clamping groove 1301, so that the armrest 3 and the rotating disk 13 are in a rotational synchronization state.

[0042] It needs to be further explained that, in the storage state, the linkage pin 17 is plugged into the second snap-in groove 1302 to limit the position of the rotating disk 13, so that the snap-in pin 14 can be aligned with the first snap-in groove 1301 during the process of pulling the handrail frame 3 out of the first slide groove 6.

[0043] As a further embodiment of the present invention, it also includes a positioning component, the positioning component includes Two positioning frames 18, the two positioning frames 18 are respectively slidably connected to the surfaces of the two handrail frames 3, and the bottom ends thereof are in frictional contact with the top surface of the extension platform 7; Two cam wheels 19, the two cam wheels 19 are rotatably connected to the top ends of the side walls of the two handrail frames 3; Two linkage plates 20 are respectively slidably plugged into the top ends of the side walls of the positioning frame 18 , and elastic telescopic rods 21 are fixedly connected to the positioning frame 18 . The tops of the linkage plates 20 are in contact with the distal ends of the cam wheels 19 .

[0044] It should be understood that during use, the staff can operate the handle 4 to drive the handrail frame 3 to move, and synchronously drive the moving seat 2 to move, thereby adjusting the position of the handle 4, and adjusting the position of the handle 4 according to the movement of the staff on the support pedal 1, which is convenient for the staff to flexibly adjust according to the actual position to be supported, and is convenient for use; It should be further explained that when the handle 4 is moved to the ideal position, the cam wheel 19 is rotated, the cam linkage plate 20 moves downward, and the linkage plate 20 applies downward pressure to the positioning frame 18 through the elastic telescopic rod 21. The bottom end of the positioning frame 18 is in close contact with the top surface of the extension platform 7 to form a friction resistance, which is beneficial to limit the position of the handle 4, maintain the stability of the position of the handle 4, and provide further stability for the support of the staff.

[0045] As an optional embodiment of the present invention, the two ends of the handle 4 are respectively connected to the top ends of the handrail frames 3 on both sides through a connecting assembly, and the connecting assembly includes: The plug-in port 22 is provided on the side wall of the cam wheel 19; The plug-in prism 23 is elastically and telescopically connected to the end of the handle 4 , and the plug-in prism 23 is plugged into the plug-in port 22 to achieve a detachable connection between the handle 4 and the armrest 3 .

[0046] It should be noted that by providing the plug-in interface 22 and the plug-in prism 23, a detachable connection between the handle 4 and the top of the handrail frame 3 is achieved; Specifically, a connection groove slidably connected to the plug-in prism 23 is formed at the end of the handle 4, and a return spring 24 is fixedly connected between the plug-in prism 23 and the inner wall of the connection groove, thereby realizing an elastic telescopic connection of the plug-in prism 23 at the end of the handle 4.

[0047] As a further embodiment of the present invention, it also includes: A limit pin 25, the limit pin 25 is slidably connected to the top of one of the handrail frames 3; The limiting groove 26 is provided on the proximal surface of the cam wheel 19 near the position of the limiting pin 25 to cooperate with the limiting pin 25 to achieve the limiting of the cam wheel 19.

[0048] It should be understood that after the cam wheel 19 cams the linkage plate 20 downward to the ideal position, the cam wheel 19 is positioned by moving the limit pin 25 to connect with the limit groove 26, thereby preventing the handle 4 from rotating under the action of external force when in the supporting state, thereby driving the cam to rotate, which is beneficial to maintaining the stable positioning of the armrest frame 3.

[0049] As an optional embodiment of the present invention, the elastic support member includes: The mounting groove 27 is provided on the top surface of the support rail 15 , the holder 16 is slidably inserted in the mounting groove 27 , and a first support spring 28 is fixedly connected between the bottom surface and the mounting groove 27 .

[0050] It should be understood that the first support spring 28 is provided to provide elastic support for the holder 16 .

[0051] As an optional technical solution of the present invention, the card holder 16 includes: A cross-shaped slide 1601 is slidably inserted into the mounting groove 27, and a side end thereof is fixedly connected to the linkage pin 17. The cross-shaped slide 1601 is connected to the mounting groove 27 via a first support spring 28; The clamping slot block 1602 is fixedly connected to the end of the cross-shaped slide seat 1601 and is sleeved on the outer surface of the fourth slide block 12, and one end of the clamping slot block 1602 is provided with a guiding inclined surface.

[0052] It should be understood that, under the support of the first support spring 28, the height of the clamping slot block 1602 is maintained. When the fourth slider 12 moves through the clamping slot block 1602, the fourth slider 12 will first squeeze the guiding slope to lower the height of the clamping. Then, when the fourth slider 12 moves to the top of the clamping slot block 1602, the fourth slider 12 is pushed and clamped under the support of the first support spring 28, so as to position the fourth slider 12. It should be further explained that when it is necessary to cancel the positioning of the fourth slider 12, the cross-shaped slide seat 1601 is pressed to drive the card slot seat to disengage from the fourth slider 12, and in the process of pressing the card slot seat, the linkage pin 17 will simultaneously disengage from the third card slot 1303, canceling the limit on the rotating disk 13, so that the support frame is free from the rotation limit.

[0053] As an optional embodiment of the present invention, a gas spring 29 is fixedly connected to the top of the snap-in pin 14 , and one end of the gas spring 29 is fixedly connected to the side wall of the handrail frame 3 via the snap-in pin 14 .

[0054] By providing the gas spring 29, the engaging state of the engaging pin 14 is supported, and under the action of external force, the engaging pin 14 can be provided with elasticity to make way. For example, in the process of pulling the supporting frame out of the first sliding groove 6, if the engaging pin 14 is not aligned with the first engaging groove 1301, the engaging pin 14 can be moved first to move the engaging pin 14 away from the docking position. After pulling it out, the supporting frame can be flipped for fine adjustment until the engaging pin 14 is aligned with the first engaging groove 1301, and then it will automatically engage with the support of the gas spring 29.

[0055] As a further embodiment of the present invention, it also includes a leg support assembly, and the leg support assembly includes: Two connecting rods 30, one end of the two connecting rods 30 is rotatably connected to the bottom end of the side wall of the supporting leg 201; A linkage slider 31, the linkage slider 31 is slidably connected to the side wall of the support leg 201, and the side wall is rotatably connected to the other ends of the two connecting rods 30; A limit slider 32, the limit slider 32 is slidably disposed in the first slide groove 6, and the limit slider 32 contacts the end of the extension platform 7; A first plug pin 33, the first plug pin 33 is fixedly connected to the side wall of the linkage slider 31; The second plug pin 34 is fixedly connected to the side wall of the limiting slider 32 , and an auxiliary support plate 35 is slidably inserted between the second plug pin 34 and the first plug pin 33 .

[0056] It should be understood that the supporting points of the supporting leg 201 are limited, and the supporting pedal 1 is easy to tip over to both sides. By providing two connecting rods 30, the bottom side direction of the supporting leg 201 is further supported, which is conducive to improving the support for the supporting pedal 1 in both sides and maintaining the stability of the supporting state of the entire supporting pedal 1. It should be further explained that, by connecting the auxiliary support plate 35 with the first plug pin 33 and the second plug pin 34, on the one hand, the supporting state of the two connecting rods 30 is maintained, and on the other hand, a triangular support is formed between the support leg 201 and the support pedal 1, which is beneficial to further improve the stability of the mutual support between the support leg 201 and the support pedal 1.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
